The correct option is One lakh caves.
Explanation
Lakhudiyar is a prominent prehistoric rock art site located on the banks of the River Suyal in the Almora district of Uttarakhand. It is historically significant for its rock shelters containing paintings that date back to the Stone Age, providing evidence of early human artistic expression in the Himalayan region.
The term 'Lakhudiyar' is derived from the local dialect, where 'Lakhu' signifies one lakh (100,000) and 'Diyar' means caves or rock shelters. Therefore, the literal translation of the name is "one lakh caves". The site is famous for its paintings depicting humans (often in stick-like forms), animals, and geometric patterns executed in red, black, and white ochre.
Key Takeaway: Lakhudiyar, literally meaning "one lakh caves," is a key site for prehistoric rock art in Uttarakhand, characterized by the superimposition of paintings and the use of distinct colors like red, black, and white.
